They get the flu shot
Getting a seasonal influenza vaccine is an excellent preventive measure for avoiding flu. Clement S. Rose, MD, an internal medicine specialist at Weiss Memorial Hospital in Chicago, gets the flu shot each year and recommends it for everyone who’s eligible. “Overall, it helps in the fight against the potentially deadly infection,” she says. Don’t fall for these habits that could mess up your flu shot.
They wash up before meals
Viruses such as the cold and flu are passed via physical contact—and you don’t have to shake hands with someone who’s sick; you could just touch a doorknob or a cell phone or a counterop that has their germs. A golden rule doctors always follow is to clean their hands before eating, with either soap and water or alcohol-based sanitizers.
